BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention generally relates to a device for manufacturing a seamless hat, more particularly to a device that provides an assembling cutting device being capable of simultaneously connecting a plurality of seam allowance cut pieces and cutting the residue of cloth in order to uniform the width of connection and be more efficient.

2. Description of the Prior Art

A prior method for manufacturing a seamless hat is described in detail as below:

-   (1) a cloth with the content of fiber must be determined at the     first is stage, then a plurality of cut pieces, which are patterned     to be with special figures in advance, are overlapped with some     edges needed to be machined; further, the edges and the cut pieces     are simply fixed each other by way of sewing so as to make initial     sewing points be distributed around the connecting edges. -   (2) The overlapped edges of the seam allowance cut piece are melted,     so that the fiber is melted as well, and the connection is then made     successfully, further that, the residue will be trimmed off. On the     other hand, if the trim is too much, a defect product may be     generated, such as hole, cave, etc.; alternatively, the continuous     process will cause bumpiness layers. -   (3) The processes of the prior method are complicated and not     beneficial to an efficient production.

Therefore, how to figure out the disadvantages of the prior arts is an important issue to the skilled people in the related field.

SUMMARY OF THE INVENTION

The disadvantages of the prior art are described as below. A cloth with the content of fiber must be determined at the first stage, then a plurality of cut pieces, which are patterned to be with special figures in advance, are overlapped with some edges needed to be machined; further, the edges and the cut pieces are simply fixed each other by way of sewing so as to make initial sewing points be distributed around the connecting edges. As a first conclusion, the initial connection is complicated. Meanwhile, the overlapped edges of the seam allowance cut piece are melted, so that the fiber is melted as well, and the connection is then made successfully, the residue will also be trimmed off, but no matter the trimmed portion is too much or less, the quality of a product will be affected comparatively. As a second conclusion, the processes of the prior method are complicated and not beneficial to an efficient production.

The primary objective of the present invention is to provide a device for manufacturing a seamless hat. The device comprises an assembling cutting device and a layer connecting device, wherein the assembling cutting device comprises an ultrasonic metal wheel, an ultrasonic metal platform, a feeding rubber wheel, and a feeding metal wheel; the ultrasonic metal wheel and the feeding rubber wheel are concentric and closed each other, a metal wheel is disposed at the bottom of the feeding rubber wheel, the ultrasonic metal platform is disposed at the bottom of the ultrasonic metal wheel, a top end of a cone peripheral surface of the ultrasonic metal wheel has a sharp edge and a platform portion, which is disposed at a side away from the rubber wheel. Accordingly, the seam allowance cut pieces of the hat may not be initially connected to the edge of the hat. And, the assembling cutting device simultaneously proceeds the ultrasonic connection of the seam allowance cut pieces and the cut to the residue of the cloth in order to uniform the connection so as to get more efficient. At last, the positions to be connected may be adhered by way of the layer connecting device wrapping around and heating the hot-welt layers in order to manufacture the seamless hat.

With references to the prior art and the present invention, the comparisons are listed as below.

-   (1) The edges and the cut pieces of the prior art are simply fixed     each other by way of sewing so as to make initial sewing points be     distributed around the connecting edges; the present invention has     no such initial connection, so that the seamless hat will be     manufactured rapidly. -   (2) The prior art adopts the way of hot-melt to connect every seam     allowance edge, if there is any residue, which must be trimmed off,     but no matter the trimmed portion is too much or less, the quality     of a product will be affected comparatively; the present invention     simultaneously proceeds the connection and the trim so as to uniform     the width of the connection. -   (3) The steps of the prior art are complicated; the present     invention is less for more efficient.
